Design and Synthesis of Linear Electo-optic Effect A* Materials

摘要日期：1994年6月1日PI: M.D. Wand机构：Displaytech， Inc。这个小型企业创新研究（SBIR）二期项目涉及设计、合成和表征温度不敏感的铁电液晶（FLC），该液晶易于排列，具有宽的操作手性近晶a范围，并显示出大的电诊所效应。这种FLCs表现出线性电光效应，允许灰度调制而不需要部分域切换。具体来说，第二阶段的研究将合成80-120个新的FLCs，测试它们诱导专有的Displaytech近晶B掺杂剂的温度不敏感性的能力，并测试和优化向列相诱导N*诱导的Displaytech掺杂剂。实现这些目标将允许制定最佳的模拟液晶混合物，这将在两个设备中进行评估，一个用于模拟光束转向应用的线性阵列调制器和一个单元件连续灰度调制器。基于温度不敏感flc的高速模拟强度调制器显示出巨大的电斜效应，将在平板显示器、模拟光束偏转器、成像光谱仪中有用的连续可调双折射滤波器和神经网络中得到应用。这些技术具有很高的当前利益和战略重要性。

Proposal: 9321110 ABSTRACT Date: 6/1/94 PI: M.D. Wand Institution: Displaytech, Inc. This Small Business Innovation Research (SBIR) Phase II project deals with the design, synthesis and characterization of temperature insensitive ferroelectric liquid crystals (FLC) which are easily aligned, have a broad operating chiral smectic A range and show a large electroclinic effect. Such FLCs show a linear electro-optic effect which permits gray modulation without partial domain switching. Specifically, the Phase II research will synthesize 80-120 new FLCs, test their ability to induce temperature insensitivity of proprietary Displaytech smectic B dopants, and test and optimize for nematic phase induction N*-inducing Displaytech dopants. Achieving these objectives will permit the formulation of the best analog liquid crystal mixture which will be evaluated in two devices, a linear array modulator for analog beam steering applications and a single element continuous grayscale modulator. High speed analog intensity modulators, based on temperature insensitive FLCs showing a large electroclinic effect will find applications in flat panel displays, analog beam deflectors, continuously tunable birefringence filters useful in imaging spectrometers, and neural networks. These technologies are of high current interest and strategic importance.
